1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesWNT10A mutations are associated with tooth agenesis. This study aimed to assess the clinical outcomes of dental implants in patients carrying WNT10A mutations with different molecular statuses and phenotypes over a long-term follow-up period. MATERIALS AND

methodsPatients with tooth agenesis were screened by whole-exome sequencing (WES) from January 2010 to September 2023. Carriers of pathogenic WNT10A mutations who underwent subsequent dental implant therapy were evaluated.

resultsWES identified 66 patients with tooth agenesis carrying WNT10A mutations. Of these, 27 patients (11 males/16 females; mean age 19.6 years) met the inclusion criteria. Homozygotes had significantly more missing teeth (24.4 ± 3.8) than heterozygotes (10.9 ± 5.1, p < 0.0001) and compound heterozygotes (13.8 ± 3.5, p = 0.001). A total of 160 conventional implants were placed. Seven implants were lost in four patients before final prosthesis placement, resulting in overall failure rates of 14.8% at the subject level and 4.4% at the implant level. The 5-year cumulative survival rate (range: 0.23-12.74 years) was 85.2% and 95.6% at the subject and implant levels, respectively. The mean marginal bone loss (MBL) was 0.80 mm (95% CI: 0.59-1.02). Subgroup analysis revealed higher MBL in homozygotes (p = 0.002), sites requiring extensive bone augmentation (p = 0.016), anterior regions (p = 0.031), and full-arch bridge cases (p < 0.0001). Patient satisfaction and OHIP-C49 scores were favorable.

conclusionsImplant rehabilitation is predictable for patients with WNT10A mutations. However, increased MBL observed in homozygotes with severe tooth agenesis and in cases requiring extensive alveolar bone augmentation highlights the importance of genetic diagnosis prior to implant therapy in patients with severe tooth agenesis.
